Classification of Regression models

		Independent variable (exposure)
		Monovariable (single variable)	Multivariable (multiple variables)
Dependent variable (outcome)	Continuous	Simple linear regression [math]\displaystyle{ Y = a + bX }[/math]	Multiple† linear regression [math]\displaystyle{ Y = a + b_1X_1 + b_2X_2 + b_3X_3 + \cdots }[/math]
	Binary	Simple binary logistic regression [math]\displaystyle{ \log Y = a + bX }[/math] where [math]\displaystyle{ Y }[/math] is odds of outcome	Multiple† binary logistic regression [math]\displaystyle{ \log Y = a + b_1X_1 + b_2X_2 + b_3X_3 + \cdots }[/math] where [math]\displaystyle{ Y }[/math] is odds of outcome
	Multinominal ≥ 3	Simple multinominal logistic regression	Multiple† multinominal logistic regression
	Ordinal	Simple ordinal logistic regression	Multiple† ordinal logistic regression
	Survival time		Multiple proportional hazard regression = Cox hazard regression

†'Multiple' can be rephrased as 'Multivariable'; NOT 'Multivariate'!!
